Personal AI Geometry Tutor Online That Teaches the Method

Photograph the diagram and the tutor asks what you can justify from what is marked on it, because geometry marks are attached to reasons rather than to conclusions and a correct answer with no justification scores very little.

Quick answer

What is the AskSia AI geometry tutor?

The AskSia AI geometry tutor is a personal tutoring tool that teaches proof and justification rather than answers. It asks what the diagram actually tells you, builds the chain of reasons with you when you ask, and puts a related configuration back to you. It covers angles and parallel lines, triangle congruence and similarity, quadrilaterals, circle theorems, area and volume, coordinate geometry and transformations. It answers in eight languages. Students on the AskSia A+ plan are covered by the Grade Confidence Guarantee. AskSia is a study aid, not an answer key.

How a session runs

Four stages, the way a tutor actually works

A solver ends when the answer appears. Tutoring ends when you can do the next one alone.

1
Hint

A nudge, not a solution

It points at the broken step and hands the problem back for your next move.

2
Walkthrough

Line by line, with the picture

Ask for more and it works through the method line by line, not just the final result.

3
Checkpoint

It asks you one back

A short question makes sure the next step belongs to you before you move on.

4
Quiz

It comes back later

Weak topics return later, when retrieval is more likely to make the method stick.

You need the answer now

It is 11pm and the set is due

Use the solver for a complete worked solution when the deadline is the priority.

You need to be able to do it

The exam is in three weeks

The tutor is slower on purpose, because it leaves a method behind for the next problem.

Where the marks go

Three habits that cost marks every semester

Geometry is the one school maths topic graded on justification. These three are where the marks go.

01

Stating a conclusion without a reason

Congruent by itself earns nothing, because the mark is attached to naming which criterion applies. The tutor asks which reason before it accepts the claim.

02

Assuming from the picture

Diagrams are rarely to scale and equal looking sides prove nothing. The tutor asks what is actually marked on the diagram.

03

Proving in the wrong order

A proof that uses a fact before establishing it is incomplete however true it is. The tutor asks what you can justify from the given information first.

Practice and tracking

Quizzes built from your mistakes, not a question bank

Your marks are not lost evenly, so your practice is not spread evenly. Try this one.

From your weak topicsCONGRUENCE
Two triangles have two pairs of equal sides and one pair of equal angles. When does this prove congruence?
Why this answer. Why B. SAS requires the angle to be included between the two sides. When the angle is not included the data can describe two different triangles, which is the ambiguous case. RHS is a separate valid criterion for right angled triangles, so option C is too narrow rather than wrong in spirit.
Long-response questions are graded on the reasoning in each step, not only the final value.
Coverage

What this tutor covers

School and introductory geometry, weighted toward the reasoning that carries the marks.

ANG
Angles and parallel lines
Which pairs are equal, and the reason to quote
TRI
Triangle congruence
SSS, SAS, ASA, RHS, and what each one needs
TRI
Triangle similarity
Ratio reasoning and scale factors
TRI
Pythagoras and its converse
Including three dimensional applications
QUAD
Quadrilaterals
Properties, and proving a shape is what you claim
CIRC
Circle theorems
Which theorem the diagram is set up for
CIRC
Tangents and chords
The theorems students most often skip
MEAS
Area, surface area and volume
Composite shapes and unit consistency
COORD
Coordinate geometry
Distance, midpoint, gradient and equations of lines
COORD
Circles in coordinates
Completing the square to find centre and radius
TRANS
Transformations
Reflection, rotation, translation, enlargement
PROOF
Writing a proof
Statement and reason, in an order that follows

Moving into trigonometry or coordinate work? Both build directly on this. Still shaky on the algebra used in coordinate geometry?

Tutoring, not a chat box

Four things a maths tutor does that a chat box does not

It knows your history, not just your question

Your next session starts with the steps that have actually been difficult, not a generic recap of the whole topic again.

It draws the diagram, not just the algebra

Diagrams are labelled and built beside every step of the working, because visual reasoning can earn marks in its own right.

It finds the first wrong line in your own working

Bring an attempt that went wrong. It finds the first step where the method changed course, then teaches that step.

It examines you the way your course does

Long-response questions need practice shaped like your own paper, not a multiple-choice bank.

Why this works

Why the answer is the smallest part of the mark

Geometry questions award marks for the chain of reasons, not the conclusion, which is why a student who can see the answer instantly can still score two out of six. The tutor refuses to accept a claim without the reason attached.

Personal here means it remembers which reasons you cannot yet name. Seeing that two triangles are congruent and knowing which criterion to quote are separate skills, and only the second one is marked.

It tutors in English, German, Japanese, Korean, Spanish, Portuguese, Simplified Chinese and Traditional Chinese, and reads photographed diagrams.

Questions

Questions students actually ask

Does it just give me the proof?

No. It asks what the diagram actually tells you and builds the chain of reasons with you. Each walkthrough ends with a related configuration put back to you.

Can it read a photographed diagram?

Yes, including your own annotations and crossings out, which is the fastest way to ask about a marked question.

Does it cover circle theorems?

Yes, and it teaches you to identify which theorem the diagram was constructed for, which is the step most students skip.

Does it help with coordinate geometry?

Yes, including completing the square to find a circle's centre and radius, which is where algebra and geometry meet most often.

Can it check a proof I wrote?

Yes. It marks the first step that uses something not yet established, which is the most common way a true proof still loses marks.

Is using an AI geometry tutor allowed?
